Claims

[Scope of utility model registration request]

(1) Separate the control unit that controls the switching element in an inverter device that once converts an AC power source into DC power and drives a switching element to generate a new AC power from the DC power source, into a first and second printed circuit board. The first printed circuit board is equipped with low-voltage circuit components such as a switching pulse generator to which the phase-to-phase voltage of the pulse for driving the switching element is not applied, and the second printed circuit board is equipped with the phase-to-phase voltage of the pulse for driving the switching element. circuit components such as a pulse amplification section to which is applied, the output section of the switching pulse generation section on the first printed circuit board, and the input section of the pulse amplification section on the second printed circuit board are isolated in terms of direct current. 1. An inverter control printed circuit board, wherein an isolator component is attached to the first and second printed circuit boards, and the first and second printed circuit boards are connected to each other by lead wires.

(2) The inverter control printed circuit board according to claim 1, wherein the second printed circuit board is a single-sided printed circuit board.
